Back again. The issue randomly stopped happening, then came right back after a windows update. I don't know if it's connected but if Opera is closing itself because of a windows security update I've got some Serious questions about what the hell it's doing to my system.

Edit : Restarting my PC again seems to have fixed the problem for now. But I shouldn't have to explain why "Restart and hope it works" isn't a solution.

Topic. Today, with no changes to a working setup, Opera started randomly quitting about a minute after it was opened. It doesn't appear to be a crash, as all the tabs I had open are reloaded with no issues. It's not limited to a tab either, as the multiple windows I routinely use all close simultaneously with no comments whatsoever.

I've tried recovering, clearing all user data, even uninstalling/reinstalling and the issue persists. I have to use firefox just to make this help request (and I hope it's in the right place, as the website conspicuously lacks any direct support). I'd like to keep using Opera, but I need it to work first.
